O ye dear friends! The world is at war and the human race is in travail and mortal combat. The dark night of hate hath taken over, and the light of good faith is blotted out. The peoples and kindreds of the earth have sharpened their claws, and are hurling themselves one against the other. It is the very foundation of the human race that is being destroyed. It is thousands of households that are vagrant and dispossessed, and every year seeth thousands upon thousands of human beings weltering in their lifeblood on dusty battlefields. The tents of life and joy are down. The generals practice their generalship, boasting of the blood they shed, competing one with the next in inciting to violence. “With this sword,” saith one of them, “I beheaded a people!” And another: “I toppled a nation to the ground!” And yet another: “I brought a government down!” On such things do men pride themselves, in such do they glory! Love—righteousness—these are everywhere censured, while despised are harmony, and devotion to the truth.

The Faith of the Blessed Beauty is summoning mankind to safety and love, to amity and peace; it hath raised up its tabernacle on the heights of the earth, and directeth its call to all nations. Wherefore, O ye who are God’s lovers, know ye the value of this precious Faith, obey its teachings, walk in this road that is drawn straight, and show ye this way to the people. Lift up your voices and sing out the song of the Kingdom. Spread far and wide the precepts and counsels of the loving Lord, so that this world will change into another world, and this darksome earth will be flooded with light, and the dead body of mankind will arise and live; so that every soul will ask for immortality, through the holy breaths of God.

The most vital duty, in this day, is to purify your characters, to correct your manners, and improve your conduct. The beloved of the Merciful must show forth such character and conduct among His creatures, that the fragrance of their holiness may be shed upon the whole world, and may quicken the dead, inasmuch as the purpose of the Manifestation of God and the dawning of the limitless lights of the Invisible is to educate the souls of men, and refine the character of every living man—so that blessed individuals, who have freed themselves from the murk of the animal world, shall rise up with those qualities which are the adornings of the reality of man. The purpose is that earthlings should turn into the people of Heaven, and those who walk in darkness should come into the light, and those who are excluded should join the inner circle of the Kingdom, and those who are as nothing should become intimates of the everlasting Glory. It is that the portionless should gain their share of the boundless sea, and the ignorant drink their fill from the living fount of knowledge; that those who thirst for blood should forsake their savagery, and those who are barbed of claw should turn gentle and forbearing, and those who love war should seek instead for true conciliation; it is that the brutal, their talons razor-sharp, should enjoy the benefits of lasting peace; that the foul should learn that there is a realm of purity, and the tainted find their way to the rivers of holiness.

In every dispensation, there hath been the commandment of fellowship and love, but it was a commandment limited to the community of those in mutual agreement, not to the dissident foe. In this wondrous age, however, praised be God, the commandments of God are not delimited, not restricted to any one group of people, rather have all the friends been commanded to show forth fellowship and love, consideration and generosity and loving-kindness to every community on earth. Now must the lovers of God arise to carry out these instructions of His: let them be kindly fathers to the children of the human race, and compassionate brothers to the youth, and self-denying offspring to those bent with years. The meaning of this is that ye must show forth tenderness and love to every human being, even to your enemies, and welcome them all with unalloyed friendship, good cheer, and loving-kindness. When ye meet with cruelty and persecution at another’s hands, keep faith with him; when malevolence is directed your way, respond with a friendly heart. To the spears and arrows rained upon you, expose your breasts for a target mirror-bright; and in return for curses, taunts and wounding words, show forth abounding love. Thus will all peoples witness the power of the Most Great Name, and every nation acknowledge the might of the Ancient Beauty, and see how He hath toppled down the walls of discord, and how surely He hath guided all the peoples of the earth to oneness; how He hath lit man’s world, and made this earth of dust to send forth streams of light.

These human creatures are even as children, they are brash and unconcerned. These children must be reared with infinite, loving care, and tenderly fostered in the embraces of mercy, so that they may taste the spiritual honey-sweetness of God’s love; that they may become like unto candles shedding their beams across this darksome world, and may clearly perceive what blazing crowns of glory the Most Great Name, the Ancient Beauty, hath set on the brows of His beloved, what bounties He hath bestowed on the hearts of those He holdeth dear, what a love He hath cast into the breasts of humankind, and what treasures of friendship He hath made to appear amongst all men.

Service to the friends is service to the Kingdom of God, and consideration shown to the poor is one of the greatest teachings of God.

Know thou of a certainty that Love is the secret of God’s holy Dispensation, the manifestation of the All-Merciful, the fountain of spiritual outpourings. Love is heaven’s kindly light, the Holy Spirit’s eternal breath that vivifieth the human soul. Love is the cause of God’s revelation unto man, the vital bond inherent, in accordance with the divine creation, in the realities of things. Love is the one means that ensureth true felicity both in this world and the next. Love is the light that guideth in darkness, the living link that uniteth God with man, that assureth the progress of every illumined soul. Love is the most great law that ruleth this mighty and heavenly cycle, the unique power that bindeth together the divers elements of this material world, the supreme magnetic force that directeth the movements of the spheres in the celestial realms. Love revealeth with unfailing and limitless power the mysteries latent in the universe. Love is the spirit of life unto the adorned body of mankind, the establisher of true civilization in this mortal world, and the shedder of imperishable glory upon every high-aiming race and nation.

Whatsoever people is graciously favored therewith by God, its name shall surely be magnified and extolled by the Concourse from on high, by the company of angels, and the denizens of the Abhá Kingdom. And whatsoever people turneth its heart away from this Divine Love—the revelation of the Merciful—shall err grievously, shall fall into despair, and be utterly destroyed. That people shall be denied all refuge, shall become even as the vilest creatures of the earth, victims of degradation and shame.

O ye beloved of the Lord! Strive to become the manifestations of the love of God, the lamps of divine guidance shining amongst the kindreds of the earth with the light of love and concord.

All hail to the revealers of this glorious light!

In cycles gone by, though harmony was established, yet, owing to the absence of means, the unity of all mankind could not have been achieved. Continents remained widely divided, nay even among the peoples of one and the same continent association and interchange of thought were wellnigh impossible. Consequently intercourse, understanding and unity amongst all the peoples and kindreds of the earth were unattainable. In this day, however, means of communication have multiplied, and the five continents of the earth have virtually merged into one. And for everyone it is now easy to travel to any land, to associate and exchange views with its peoples, and to become familiar, through publications, with the conditions, the religious beliefs and the thoughts of all men. In like manner all the members of the human family, whether peoples or governments, cities or villages, have become increasingly interdependent. For none is self-sufficiency any longer possible, inasmuch as political ties unite all peoples and nations, and the bonds of trade and industry, of agriculture and education, are being strengthened every day. Hence the unity of all mankind can in this day be achieved. Verily this is none other but one of the wonders of this wondrous age, this glorious century. Of this past ages have been deprived, for this century—the century of light—hath been endowed with unique and unprecedented glory, power and illumination. Hence the miraculous unfolding of a fresh marvel every day. Eventually it will be seen how bright its candles will burn in the assemblage of man.

Behold how its light is now dawning upon the world’s darkened horizon. The first candle is unity in the political realm, the early glimmerings of which can now be discerned. The second candle is unity of thought in world undertakings, the consummation of which will erelong be witnessed. The third candle is unity in freedom which will surely come to pass. The fourth candle is unity in religion which is the cornerstone of the foundation itself, and which, by the power of God, will be revealed in all its splendor. The fifth candle is the unity of nations—a unity which in this century will be securely established, causing all the peoples of the world to regard themselves as citizens of one common fatherland. The sixth candle is unity of races, making of all that dwell on earth peoples and kindreds of one race. The seventh candle is unity of language, i.e., the choice of a universal tongue in which all peoples will be instructed and converse. Each and every one of these will inevitably come to pass, inasmuch as the power of the Kingdom of God will aid and assist in their realization.

O thou who art turning thy face towards God! Close thine eyes to all things else, and open them to the realm of the All-Glorious. Ask whatsoever thou wishest of Him alone; seek whatsoever thou seekest from Him alone. With a look He granteth a hundred thousand hopes, with a glance He healeth a hundred thousand incurable ills, with a nod He layeth balm on every wound, with a glimpse He freeth the hearts from the shackles of grief. He doeth as He doeth, and what recourse have we? He carrieth out His Will, He ordaineth what He pleaseth. Then better for thee to bow down thy head in submission, and put thy trust in the All-Merciful Lord.

Every imperfect soul is self-centered and thinketh only of his own good. But as his thoughts expand a little he will begin to think of the welfare and comfort of his family. If his ideas still more widen, his concern will be the felicity of his fellow citizens; and if still they widen, he will be thinking of the glory of his land and of his race. But when ideas and views reach the utmost degree of expansion and attain the stage of perfection, then will he be interested in the exaltation of humankind. He will then be the well-wisher of all men and the seeker of the weal and prosperity of all lands. This is indicative of perfection.

Thus, the divine Manifestations of God had a universal and all-inclusive conception. They endeavored for the sake of everyone’s life and engaged in the service of universal education. The area of their aims was not limited—nay, rather, it was wide and all-inclusive.

Therefore, ye must also be thinking of everyone, so that mankind may be educated, character moderated and this world may turn into a Garden of Eden.

Love ye all religions and all races with a love that is true and sincere and show that love through deeds and not through the tongue; for the latter hath no importance, as the majority of men are, in speech, well-wishers, while action is the best.

If a small number of people gather lovingly together, with absolute purity and sanctity, with their hearts free of the world, experiencing the emotions of the Kingdom and the powerful magnetic forces of the Divine, and being at one in their happy fellowship, that gathering will exert its influence over all the earth. The nature of that band of people, the words they speak, the deeds they do, will unleash the bestowals of Heaven, and provide a foretaste of eternal bliss. The hosts of the Company on high will defend them, and the angels of the Abhá Paradise, in continuous succession, will come down to their aid.

The prime requisites for them that take counsel together are purity of motive, radiance of spirit, detachment from all else save God, attraction to His Divine Fragrances, humility and lowliness amongst His loved ones, patience and long-suffering in difficulties and servitude to His exalted Threshold. Should they be graciously aided to acquire these attributes, victory from the unseen Kingdom of Bahá shall be vouchsafed to them.

Marriage, among the mass of the people, is a physical bond, and this union can only be temporary, since it is foredoomed to a physical separation at the close.

Among the people of Bahá, however, marriage must be a union of the body and of the spirit as well, for here both husband and wife are aglow with the same wine, both are enamored of the same matchless Face, both live and move through the same spirit, both are illumined by the same glory. This connection between them is a spiritual one, hence it is a bond that will abide forever. Likewise do they enjoy strong and lasting ties in the physical world as well, for if the marriage is based both on the spirit and the body, that union is a true one, hence it will endure. If, however, the bond is physical and nothing more, it is sure to be only temporary, and must inexorably end in separation.

When, therefore, the people of Bahá undertake to marry, the union must be a true relationship, a spiritual coming together as well as a physical one, so that throughout every phase of life, and in all the worlds of God, their union will endure; for this real oneness is a gleaming out of the love of God.

In the same way, when any souls grow to be true believers, they will attain a spiritual relationship with one another, and show forth a tenderness which is not of this world. They will, all of them, become elated from a draught of divine love, and that union of theirs, that connection, will also abide forever. Souls, that is, who will consign their own selves to oblivion, strip from themselves the defects of humankind, and unchain themselves from human bondage, will beyond any doubt be illumined with the heavenly splendours of oneness, and will all attain unto real union in the world that dieth not.

The education and training of children is among the most meritorious acts of humankind and draweth down the grace and favor of the All-Merciful, for education is the indispensable foundation of all human excellence and alloweth man to work his way to the heights of abiding glory. If a child be trained from his infancy, he will, through the loving care of the Holy Gardener, drink in the crystal waters of the spirit and of knowledge, like a young tree amid the rilling brooks. And certainly he will gather to himself the bright rays of the Sun of Truth, and through its light and heat will grow ever fresh and fair in the garden of life.

Therefore must the mentor be a doctor as well: that is, he must, in instructing the child, remedy its faults; must give him learning, and at the same time rear him to have a spiritual nature. Let the teacher be a doctor to the character of the child, thus will he heal the spiritual ailments of the children of men.

If, in this momentous task, a mighty effort be exerted, the world of humanity will shine out with other adornings, and shed the fairest light. Then will this darksome place grow luminous, and this abode of earth turn into Heaven. The very demons will change to angels then, and wolves to shepherds of the flock, and the wild-dog pack to gazelles that pasture on the plains of oneness, and ravening beasts to peaceful herds, and birds of prey, with talons sharp as knives, to songsters warbling their sweet native notes.

For the inner reality of man is a demarcation line between the shadow and the light, a place where the two seas meet; it is the lowest point on the arc of descent, and therefore is it capable of gaining all the grades above. With education it can achieve all excellence; devoid of education it will stay on, at the lowest point of imperfection.

Every child is potentially the light of the world—and at the same time its darkness; wherefore must the question of education be accounted as of primary importance. From his infancy, the child must be nursed at the breast of God’s love, and nurtured in the embrace of His knowledge, that he may radiate light, grow in spirituality, be filled with wisdom and learning, and take on the characteristics of the angelic host.

O Friends of the Pure and Omnipotent God! To be pure and holy in all things is an attribute of the consecrated soul and a necessary characteristic of the unenslaved mind. The best of perfections is immaculacy and the freeing of oneself from every defect. Once the individual is, in every respect, cleansed and purified, then will he become a focal center reflecting the Manifest Light.

First in a human being’s way of life must be purity, then freshness, cleanliness, and independence of spirit. First must the stream bed be cleansed, then may the sweet river waters be led into it. Chaste eyes enjoy the beatific vision of the Lord and know what this encounter meaneth; a pure sense inhaleth the fragrances that blow from the rose gardens of His grace; a burnished heart will mirror forth the comely face of truth.

This is why, in Holy Scriptures, the counsels of heaven are likened to water, even as the Qur’án saith: “And pure water send We down from Heaven,” 1 and the Gospel: “Except a man be baptized of water and of the spirit, he cannot enter into the Kingdom of God.” Thus is it clear that the Teachings which come from God are heavenly outpourings of grace; they are rain-showers of divine mercy, and they cleanse the human heart.

My meaning is this, that in every aspect of life, purity and holiness, cleanliness and refinement, exalt the human condition and further the development of man’s inner reality. Even in the physical realm, cleanliness will conduce to spirituality, as the Holy Writings clearly state. And although bodily cleanliness is a physical thing, it hath, nevertheless, a powerful influence on the life of the spirit. It is even as a voice wondrously sweet, or a melody played: although sounds are but vibrations in the air which affect the ear’s auditory nerve, and these vibrations are but chance phenomena carried along through the air, even so, see how they move the heart. A wondrous melody is wings for the spirit, and maketh the soul to tremble for joy. The purport is that physical cleanliness doth also exert its effect upon the human soul.

There are two ways of healing sickness, material means and spiritual means. The first is by the treatment of physicians; the second consisteth in prayers offered by the spiritual ones to God and in turning to Him. Both means should be used and practiced.

Illnesses which occur by reason of physical causes should be treated by doctors with medical remedies; those which are due to spiritual causes disappear through spiritual means. Thus an illness caused by affliction, fear, nervous impressions, will be healed more effectively by spiritual rather than by physical treatment. Hence, both kinds of treatment should be followed; they are not contradictory. Therefore thou shouldst also accept physical remedies inasmuch as these too have come from the mercy and favor of God, Who hath revealed and made manifest medical science so that His servants may profit from this kind of treatment also. Thou shouldst give equal attention to spiritual treatments, for they produce marvelous effects.

Now, if thou wishest to know the true remedy which will heal man from all sickness and will give him the health of the divine kingdom, know that it is the precepts and teachings of God. Focus thine attention upon them.

If humankind were free from the defilements of sin and waywardness, and lived according to a natural, inborn equilibrium, without following wherever their passions led, it is undeniable that diseases would no longer take the ascendant, nor diversify with such intensity.

But man hath perversely continued to serve his lustful appetites, and he would not content himself with simple foods. Rather, he prepared for himself food that was compounded of many ingredients, of substances differing one from the other. With this, and with the perpetrating of vile and ignoble acts, his attention was engrossed, and he abandoned the temperance and moderation of a natural way of life. The result was the engendering of diseases both violent and diverse.

For the animal, as to its body, is made up of the same constituent elements as man. Since, however, the animal contenteth itself with simple foods and striveth not to indulge its importunate urges to any great degree, and committeth no sins, its ailments relative to man’s are few. We see clearly, therefore, how powerful are sin and contumacy as pathogenic factors. And once engendered these diseases become compounded, multiply, and are transmitted to others. Such are the spiritual, inner causes of sickness.

The outer, physical causal factor in disease, however, is a disturbance in the balance, the proportionate equilibrium of all those elements of which the human body is composed. To illustrate: the body of man is a compound of many constituent substances, each component being present in a prescribed amount, contributing to the essential equilibrium of the whole. So long as these constituents remain in their due proportion, according to the natural balance of the whole—that is, no component suffereth a change in its natural proportionate degree and balance, no component being either augmented or decreased—there will be no physical cause for the incursion of disease.

O ye respected souls! From the continual imitation of ancient and worn-out ways, the world had grown dark as darksome night. The fundamentals of the divine Teachings had passed from memory; their pith and heart had been totally forgotten, and the people were holding on to husks. The nations had, like tattered garments long outworn, fallen into a pitiful condition.

Out of this pitch blackness there dawned the morning splendor of the Teachings of Bahá’u’lláh. He hath dressed the world with a garment new and fair, and that new garment is the principles which have come down from God.

Now the new age is here and creation is reborn. Humanity hath taken on new life. The autumn hath gone by, and the reviving spring is here. All things are now made new. Arts and industries have been reborn, there are new discoveries in science, and there are new inventions; even the details of human affairs, such as dress and personal effects—even weapons—all these have likewise been renewed. The laws and procedures of every government have been revised. Renewal is the order of the day.

And all this newness hath its source in the fresh outpourings of wondrous grace and favor from the Lord of the Kingdom, which have renewed the world. The people, therefore, must be set completely free from their old patterns of thought, that all their attention may be focused upon these new principles, for these are the light of this time and the very spirit of this age.

Unless these Teachings are effectively spread among the people, until the old ways, the old concepts, are gone and forgotten, this world of being will find no peace, nor will it reflect the perfections of the Heavenly Kingdom. Strive ye with all your hearts to make the heedless conscious, to waken those who sleep, to bring knowledge to the ignorant, to make the blind to see, the deaf to hear, and restore the dead to life.

It behooveth you to show forth such power, such endurance, as to astonish all beholders. The confirmations of the Kingdom are with you. Upon you be the glory of the All-Glorious.
